What type of serial cable? (controller to servo box)

Hey everyone,

I am going to be linking our servo control box to the controller of our VF-4, i talked to our HFO and he said they do not offer the cable we need.
From what they said, i need a sheilded straight through serial cable, i assume we will need male connectors on both ends. I'm sure we're not the only ones doing this, maybe you guys can give me some guidance. I am a bit leery of buying it from places like amazon and getting a terrible product. Also we would need at least 15 or so feet of the stuff, which doesn't seem too easy to come by.

Thanks for any help you can offer,


-Tony


edit: we will be linking the controller to the box so we can index without an operator there.
